The present invention relates to coal chemical technologies.A kind of preparation method for the dual-function composite catalyst preparing light aromatics for benzene and one-step method from syngas, the dual-function composite catalyst are made of acidic molecular sieve and metal oxide, and the mass ratio of acidic molecular sieve and metal oxide is 0.5 ~ 10ï¼›Wherein acidic molecular sieve is HZSM-5 molecular sieve, and metal oxide is that transition metal Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Mo, In, W, Re one or more of work as, and prepares the dual-function composite catalyst by ball milling mixing.The dual-function composite catalyst can be used in carbon monoxide, in the reacting of hydrogen and benzene alkylation light aromatics. |
